Antwort Should I learn Java 17 or 11? Weitere Antworten – Should I learn Java 11 or Java 17
As a newbie, it is recommended to start with the latest version of Java, which is Java 17 as of my knowledge cutoff. The latest version has the most up-to-date features and bug fixes. However, Java 8 and Java 11 are also popular and widely used versions, so they are also good options.The Parallel Garbage Collector(Available in Java 17) is 16.39% faster than the G1 Garbage Collector(Used in Java 11). Migrating from Java 11 to Java 17 can provide many benefits, including new features and improved performance.As for Java 18, there is only a six-month time difference between it and Java 17, which means the updates aren't as trascendental or numerous as we've been able to see with other releases. However, Java 18 has improvements in terms of its foreign function memory.
Why Java 11 is better : Java 11 has improved garbage collection due to garbage collectors like ZGC and Epsilon. Thus, applications in Java 11 are faster and more secure than in Java 8.
Why is Java 17 better than Java 11
Java 17 enhances coding with features like Text Blocks for multiline text, Records for data-safe classes, enhanced Switch Expressions, and Pattern Matching for instanceof.
Why migrate from Java 11 to Java 17 : There are several reasons to migrate from JDK 11 to JDK 17 as outlined below: Improved performance and stability: JDK 17 introduces many new features, optimizations, and bug fixes that can enhance the performance and stability of your applications.
Improved Security
It is critical that your applications are secure. In Java 17 there are upgraded security features that help protect users' data and ensure application integrity. Many known security vulnerabilities in previous Java versions have been resolved.
Java 17 provides multiple security updates, including improved TLS 1.3 support, updated cryptographic algorithms, and fixes for potential vulnerabilities found in earlier versions. Upgrading to Java 17 ensures that your application is secure and protected against potential threats.
Is Java 11 still supported
Java 11 was released in September 2018; premier support ends in September 2023 and extended support will terminate September 2026.Every two to three years a Java release is designated as long-term support (LTS) and receives quarterly stability, security, and performance updates only—not new features. More than 56% of applications are now using Java 11 in production (up from 48% in 2022 and 11% in 2020).Java is fairly easy to learn if you have already studied another programming language. However, if Java is your first, it will be a little more complicated. For a person learning to code for the first time, one challenge when learning Java can be getting the hang of the language's syntax.

| Oracle Java SE Support Roadmap*† | ||
|---|---|---|
| Release | GA Date | Premier Support Until |
| 11 (LTS) | September 2018 | September 2023 |
| 12 – 16 (non-LTS) | March 2019 – March 2021 | September 2019 – September 2021 |
| 17 (LTS) | September 2021 | September 2026**** |
How long will Java 17 be supported : Java 17 was released in September 2021 and is slated to receive premier support through 2026 with extended support sunsetting by September 2029.
Should I move to Java 11 : If the goal is to get an application up and running as quickly as possible, just trying to run on Java 11 is often the best approach. For a library, the goal will be to publish an artifact that is compiled and tested with JDK 11. Moving to Java 11 is worth the effort.
Should I upgrade to Java 11
Upgrading from Java 8 to Java 11 offers several benefits and improvements. Here are some of the key reasons why you should consider upgrading: Improved performance and security: Java 11 offers better performance and security enhancements over Java 8, including support for newer hardware and cryptographic algorithms.
Applications written in Java 11 are faster and more secure than Java 8 as it upgraded to support TLS 1.3, which is more secure than the previous versions. Also, CORBA and Java EE modules have been removed from Java 11 to tackle security issues. So, one should upgrade from Java 8 to Java 11.The LTS versions are 8, 11, 17 and 21. Non-LTS versions are not supported as soon as the next release is published (so basically after ~6 months). All versions are "stable" since they all pass the TCK.
Why Java 17 after Java 11 : Java's competitive advantage shines here as backward compatibility allows you to switch to Java 17 without any code changes and take advantage of all the updated features. Version 17 is a Long-term Support version, ensuring you receive all the necessary security updates for an extended period.
